Vishay - Power SMD White LEDs in Thermally Enhanced PLCC-4 Package Feature Two Binning Versions, High Luminous Intensity to 3550 mcd, and Thermal Resistance Down to 300 K/W
Vishay announced the release of new power surface-mount white LEDs in two binning versions. For a wider range of pin compatibility with similar devices, the VLMW321xx LEDs feature three anodes and one cathode, while the VLMW322xx LEDs offer three cathodes and one anode.
The The high-intensity LEDs are intended for traffic signals and signs; interior and exterior lighting; automotive interior and exterior lighting; indicators and backlighting in household appliances, toys and games, and mobile phones; camera flashes; and general illumination for retail and window displays, emergency lighting and signs, and museums and showrooms.
Built on high-efficiency InGaN technology, the VLMW321xx and VLMW322xx devices provide a high luminous intensity of 1400 mcd to 3550 mcd, and luminous flux from 7000 mlm to 8900 mlm. The LEDs feature a 60° angle of half-intensity and a luminous intensity ratio per packing unit of less than 1.6, and are categorized, per packing unit, for luminous intensity and color.
The lead (Pb)-free and RoHS-compliant devices are available in 8-mm tape and are compatible with IR-reflow, vapor phase, and wave soldering processes according to CECC 00802 and J-STD-020, and preconditioning according to JEDEC Level 2a. The LEDs offer an ESD-withstand voltage up to 2 kV (HBM) according to JESD22-A114-B.
